This was an immense semicircular structure, the largest of which any account has come down to us from ancient times. It was open to the sky, with ascending seats, tier above tier, and is said to have been capable of holding thirty thousand persons. Its ruins are yet to be seen.

Hence it was perfectly natural for the excited multitude to rush into the theater on this occasion.
